Seachem Flourish Phosphorus 100ml

Unlike other similar products, which contain a mixture of nitrates and phosphates, Flourish Phosphorus allows phosphorus to be administered in the optimum amount for plants without the risk of raising nitrate levels. When used as directed, it accelerates the growth of aquatic plants. It is recommended to use it together with Flourish Nitrogen and Flourish Potassium.

Directions for use:

Beginners: 2.5 ml (half a capful) for every 80 litres of tank capacity, once or twice a week as needed. Phosphorus deficiency is manifested, among others, by stunted growth and dark green colouring of shoots.

Advanced: The dose recommended for beginners increases phosphorus levels by 0.05 mg/l (0.15 mg/l for phosphates). The optimum level of this element may vary depending on the planting of the aquarium, but is usually between 0.15 and 1.0 mg/l. It is recommended to check the phosphate level with a suitable test. The following formula may be helpful in obtaining the correct phosphorus level: 0.2vp=m, where v= volume of tank in litres, p= planned increase in phosphorus level, m= volume of Flourish Phosphorus preparation. For example, if you want to increase the phosphorus level to 0.1mg/l in a tank of 80 litres, you need to add 0.2x80x0.1=1.6 ml of preparation.

Guaranteed composition: Total phosphate (P2O5) 0.3% Soluble potassium oxide (K2O) 0.2%
